The Flowtrail Schwarzsee offers pure biking fun in the middle of the Fribourg Prealps. With flowing corners, small waves, and dreamlike views of the Schwarzsee, the trail is perfect for those who want to combine riding pleasure and nature. Whether as a relaxed after-work loop or a sporty trail adventure – every mountain bike fan will get their money's worth here. Between Riggisalp and Schwarzsee, the trail leads through a varied landscape of forests, pastures, and impressive views of the lake and mountains. With a length of 3.6 kilometers and 427 meters of descent, the trail is classified as moderately difficult in the upper section and easy further down. A separate entrance to the lower section (Start Blau) provides families and beginners with younger children with particularly easy access. A gentle track with playfully designed obstacles ensures a smooth, relaxed riding experience on the bike. Those looking for more action will find additional, technically more demanding elements along the route. These are deliberately designed so that less experienced riders can easily bypass them at any time via a "Safe Line".

Yes, this climb on the Way of St. James is tough...not suitable for inexperienced bikers - very steep and rocks which can be slippery
